R21xx-HP FlexFabric 11900 Layer 3 IP Services Command Reference
189
• If the interface has no IPv6 global unicast address configured, it has no link-local address.
Manual assignment takes precedence over automatic generation.
• If you first adopt automatic generation and then manual assignment, the manually assigned
link-local address overwrites the automatically generated address.
• If you first use manual assignment and then automatic generation, the automatically generated
link-local address does not take effect and the link-local address of an interface is still the manually
assigned address.
If you delete the manually assigned address, the automatically generated link-local address is validated.
For more information about manually assignment of an IPv6 link-local address, see the ipv6 address
link-local command.

# Configure VLAN-interface 100 to automatically generate a link-local address.
